ROAD-DRAG.

Specification of Letters Patent.

iatented Mar. 15, 1921;

To ZZ wlw/m t may concer/n:

Be it known that we, lViLLiiiii H. BAn'i'ELL and HENRY C. LonsoH,citizens of the United States, residing at Colorado Springs, in thecounty of El Paso and State of Colorado, have invented' certain new anduseful Improvements in Road-Drags, of which the following is aspecification.

This invention relates to newA and useful improvements in road drags,and the 'primary object of the invention is to provide a road drag' ofthis character, provided with iiieans whereby thel drag bars maybecapable of various adjustments as is obvious.

Another object of the invention is to provide a road drag of thischaracter', formed `of oppositely disposed scraper sections, providedwith reversible angularly adjustable drag bars, said sections beingcapable of various adjustments with respect to each other, either toscrape the dirt toward the center' of the road, or to either sidethei'eof.

A further object of the invention is to provide a device of thischaracter, which is easily and simply constructed, inexpensive tomanufacture, and one which will be very eiiicient in operation.

lith these and numerous other objects in view, our invention consists ofthe novel features of construction, combination and arrangement of partswhich will be herein referred to, and more particularly pointed out inthe speciiication and claim.

In the accompanying drawings:

Figure 1 is a top plan View of theroad drag; j Y

Fig. 2 is an end elevation thereof;

Fig. 3 is a detail perspective view of one of the connecting meansbetween the drag bars, and connecting rods; and

Fig. 4 are diagrammatic views of various positions in which the scrapersections may be placed.

In describing our invention, we shall refer to the drawings in whichsimilar reference characters designate corresponding parts throughoutthe several views.

The drag` is formed of two scraper sections designated by the numerals1V and 2, which are each formed of a plurality of parallel drag bars 3.The scraper section 1 has the parallel drag` bars 3 connectedintermediate, the ends of the same by spaced parallel connecting rods 4,preferably formed of angle iron, and end connecting rods 5, which arebent, as clearly shown in Fig. 1 of the draw# ed to rock, when therocking means are ap-' plied as will beV hereinafter more fullydescribed. The opposite parallel connecting rods 4 are connected withthe end connecting rods 5, by ycross connected link membersy 9 and 10. YY j .Y 'Y

Projecting upwardly between the spaced connecting rods 4, that arekcentrally disposed with respect to the scraper section 1, are arinsr11,having feet 12 on their lowerends secured to the angle Airon 6, saidarms 11 extending above the arms 8, and having their upper endsconnectedby a transversely extending bar 12. The bar 12 has its rearextremity connected to a pivoted lever V13 mounted on the taperedsection, said lever being adapted to be locked in various adjustedpositions by means of lan arcuate rack member 14, provided with avplurality of apertures, adapted for alinement with an aperturethrouglitlie lever, a pin insertible Y therethrough to hold the lever invarious adjusted positions. in position on the rear end `of the scrapersection l, by projecting arms 15, as clearly shown in Fig. 2 of thedrawings.

The scraper section 2 is substantially similar to the section 1, exceptthat Vthe center connecting rods which are designated by the numeral 16are curved to conform to the therewith are similar to the means employedon the sections 1, and additional descriptiony thereof andthe otherparts of this scraper" The rack 14-is securedVVV curvature of the outerconnectingrods 17 The lever and locking means associated with the powerused to pull the drag and by varying the length of the chains the various adjustments suggested in Fig. f1 may be obtained, the link 18maintaining the sections in properly spaced relation.

In operation, the drag bars 3 are normally disposed upright, as shown inFigs. l and 2 of the drawings, when it is desired to shift the same, thelocking pin that locks theV lever to the rack 14 is removed, and thelever 13 swung `in either direction. This will rock the bars 3, as thesame are connected by the bar 12, arms 11, and angle iron G to the dra@bars.

llihen the desired adjustment has been made, the lever 13,is locked inposition, by inserting the locking pin through the alining apertures,and the drag bars will be locked in various angular-ly adjustedpositions. The connected rods 1l and 5,and 16 and 17 of the sections,are held rigid7 above the` swingable bars 3, and the draft'connectionsof the device are made to these trames.

From the above description taken in connection with the accompanyingdrawings, it is thought that a clear and comprehensive understanding ofthe construction, operation, and advantages of. our invention may behad, and while we have shown and .described the device as embodying aspeciiic structure, we desire that it be understood that such changesmay be made in said structure as do not depart from the spirit and scopeof the invention as claimed.

Having fully described our invention what we claim as new, and desire tosecure by Letters Patent is:

In a road drag, scraper sections, said sections comprisingA a pluralityof parallel scraper bars, angle bars connected to the scraper bars,upstanding arms rigidly connected with the angle bars angularly bentconnecting rods connecting the upper termi nals of said arms, relativelylong arms connected medially with the angle bars, two of said angularlybent connecting rods being arranged on opposite sides of the relativelylong arms, said sections being movable into alinement or various angularpositions, an

adjustable spacing member connecting the inner angu'larly bentconnecting rods in `proximity to the rear scraper bars, and flexible d.'a'ft members connected with the opposite terminals ot each, sectionfor anglingor straightening the sections by the pull ot the draftanimals.

In testimony whereof, we aiiix our signatures hereto.

WILLIAM Ifl. BARTELL. HENRY C. LOESCH.
